Model:

Designed as a direct replacement for the
OEM valve which is prone to
failure when the engine has been tuned or had an upgrade to the engine
management software. This valve is complete and ready to install with
no fitting kit required.

This valve is suitable for:

Ford Focus RS Mk2

Ford Focus ST Mk2

Volvo
C30 T5 and S70 T5

Porsche 997 (Please order two valves)

These dump valves are built with
the green spring fitted as standard, this is suitable for OEM cars and
small boost increases over standard. If you want a higher pressure
spring supplied instead please choose the relevant option in the drop
down menu (otherwise pick green). You will not be charged any extra , if
you want a selection of springs please follow the associated link below
to purchase extra springs.

Valve Spring
color coding

Green - 6-8 PSI

Yellow -
10-12 PSI

Blue
- 14-16 PSI

Red
- 18-20 PSI

Please
Note:

The
quoted spring pressure (Psi) relates to the un-assisted clamping force
of the spring and should NOT be taken as an equivalent to boost pressure
when determining suitability.
Once a valve is fitted to a car
it is subjected to various pressures that act upon the diaphragm or
piston to aid its respective ability to seal or hold boost.

A guide to correct
spring choice:

The guide below is very 'rule of
thumb' and should not be taken as literal. Each car and tuning package
may react differently, find out the approximate peak boost your car
produces and use this to select the most appropriate spring, you should
also refer to the notes below if you are concerned the spring you are
using may be too hard or too soft.

Green – up to 10psi
(supplied with this spring installed).

Yellow – 10psi to 16psi.

Blue -
16psi to 22psi.

Red
- 22psi and up.

If you are unsure of the
suitability of the spring you have installed you should look for the
following symptoms:

·With a spring that is too weak
the boost
pressure will noticeably drop off in the lower gears anywhere from 2500
rev’s upwards.

·Alternatively, a spring that is too
strong will induce compressor stall when changing gear which is probably
best
described as a flat spot as the next gear is engaged. Most customers
will be
used to a smooth transition of power between the gear changes in the
standard
engine and will noticeably sense a sluggish pick up between the gear
changes.
